When grown in masses or used as a bedding plant, individual plants should be spaced approximately 16 inches apart. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 5 years.
This plant should be grown in a location that is shaded from the hot afternoon sun. It prefers to grow in moist to wet soil, and will even tolerate some standing water. It is not particular as to soil pH, but grows best in rich soils. It is somewhat tolerant of urban pollution. This is a selection of a native North American species, and parts of it are known to be toxic to humans and animals, so care should be exercised in planting it around children and pets. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
